One of the tours that many people go on, while in Ketchikan is the crab boat tour. It’s about a 3.5 to 4 hour tour. I have been on it 4 or 5 times, usually taking someone who is visiting us. The ship is the Aleutian Ballad. The crew takes you out, shows you how crab pots work, they have some preset ones that they pull you for you. They show you different types of crab also from small ones to kings. The tour is very informative and the crew is very friendly.
At one point they attract some bald eagles. I have seen over 30 flying around the ship and feeding from the water, but toward the end of the season I have seen less than 10. They give you the opportunity to hold various sea creatures, if you want. This is a rain or shine tour. Best place is on top deck to get some good eagle pictures, on the bottom deck if you want to handle stuff. I believe that there are age restrictions for small kids.
